Hush Begins Crowdfunding to Produce Noise-Masking “Smart Earplugs”

Hush, a San Diego startup that has developed “smart earbuds” to minimize the distractions of a noisy world, is beginning a crowdfunding campaign today that would enable the year-old company to produce as many as 10,000 units by spring.

The result was an earplug that would block out the world, yet allow users to … Next Page »

  • Designing of earplugs is quite crucial, they require expertise because they have NRR(Noise reduction Ratio) which varies from one earplug to the other.
